#	As of 2.0.0, FreeRADIUS supports virtual hosts using the

#	"server" section, and configuration directives.

#

#	Virtual hosts should be put into the "sites-available"

#	directory.  Soft links should be created in the "sites-enabled"

#	directory to these files.  This is done in a normal installation.

#

#	$Id$

#

######################################################################

#

#	Read "man radiusd" before editing this file.  See the section

#	titled DEBUGGING.  It outlines a method where you can quickly

#	obtain the configuration you want, without running into

#	trouble.  See also "man unlang", which documents the format

#	of this file.

#

#	This configuration is designed to work in the widest possible

#	set of circumstances, with the widest possible number of

#	authentication methods.  This means that in general, you should

#	need to make very few changes to this file.

#

#	The best way to configure the server for your local system

#	is to CAREFULLY edit this file.  Most attempts to make large

#	edits to this file will BREAK THE SERVER.  Any edits should

#	be small, and tested by running the server with "radiusd -X".

#	Once the edits have been verified to work, save a copy of these

#	configuration files somewhere.  (e.g. as a "tar" file).  Then,

#	make more edits, and test, as above.

#

#	There are many "commented out" references to modules such

#	as ldap, sql, etc.  These references serve as place-holders.

#	If you need the functionality of that module, then configure

#	it in radiusd.conf, and un-comment the references to it in

#	this file.  In most cases, those small changes will result

#	in the server being able to connect to the DB, and to

#	authenticate users.

######################################################################

#

#	In 1.x, the "authorize", etc. sections were global in

#	radiusd.conf.  As of 2.0, they SHOULD be in a server section.

#

#	The server section with no virtual server name is the "default"

#	section.  It is used when no server name is specified.

#

#	We don't indent the rest of this file, because doing so

#	would make it harder to read.

#

#  Authorization. First preprocess (hints and huntgroups files),

#  then realms, and finally look in the "users" file.

#

#  The order of the realm modules will determine the order that

#  we try to find a matching realm.

#

#  Make *sure* that 'preprocess' comes before any realm if you

#  need to setup hints for the remote radius server

authorize {

	#

	#  The preprocess module takes care of sanitizing some bizarre

	#  attributes in the request, and turning them into attributes

	#  which are more standard.

	#

	#  It takes care of processing the 'raddb/hints' and the

	#  'raddb/huntgroups' files.

	#

	#  It also adds the %{Client-IP-Address} attribute to the request.

	#  If you want to have a log of authentication requests,

	#  un-comment the following line, and the 'detail auth_log'

	#  section, above.

#	auth_log

	#

	#  The chap module will set 'Auth-Type := CHAP' if we are

	#  handling a CHAP request and Auth-Type has not already been set

#	chap

	#

	#  If the users are logging in with an MS-CHAP-Challenge

	#  attribute for authentication, the mschap module will find

	#  the MS-CHAP-Challenge attribute, and add 'Auth-Type := MS-CHAP'

	#  to the request, which will cause the server to then use

	#  the mschap module for authentication.

	#  If you are using multiple kinds of realms, you probably

	#  This module takes care of EAP-MD5, EAP-TLS, and EAP-LEAP

	#  authentication.

	#

	#  It also sets the EAP-Type attribute in the request

	#  attribute list to the EAP type from the packet.

	#

	#  As of 2.0, the EAP module returns "ok" in the authorize stage

	#  for TTLS and PEAP.  In 1.x, it never returned "ok" here, so

	#  this change is compatible with older configurations.

	#

	#  The example below uses module failover to avoid querying all

	#  of the following modules if the EAP module returns "ok".

	#  Therefore, your LDAP and/or SQL servers will not be queried

	#  for the many packets that go back and forth to set up TTLS

	#  or PEAP.  The load on those servers will therefore be reduced.

	#  If no other module has claimed responsibility for

	#  other modules listed above to add a "known good" password

	#  to the request, and to do nothing else.  The PAP module

	#  will then see that password, and use it to do PAP

	#  authentication.

	#  This module should be listed last, so that the other modules

	#  get a chance to set Auth-Type for themselves.

#  Authentication.

#

#

#  This section lists which modules are available for authentication.

#  Note that it does NOT mean 'try each module in order'.  It means

#  that a module from the 'authorize' section adds a configuration

#  attribute 'Auth-Type := FOO'.  That authentication type is then

#  used to pick the apropriate module from the list below.

#

#  In general, you SHOULD NOT set the Auth-Type attribute.  The server

#  will figure it out on its own, and will do the right thing.  The

#  most common side effect of erroneously setting the Auth-Type

#  attribute is that one authentication method will work, but the

#  others will not.

#

#  The common reasons to set the Auth-Type attribute by hand

#  is to either forcibly reject the user (Auth-Type := Reject),

#  or to or forcibly accept the user (Auth-Type := Accept).

#

#  Note that Auth-Type := Accept will NOT work with EAP.

#

#  Please do not put "unlang" configurations into the "authenticate"

#  section.  Put them in the "post-auth" section instead.  That's what

#  the post-auth section is for.
